Like a more realistic, grounded take on “The 6th Day” or “Criminal” (and, to a lesser extent, “Total Recall,” “Gemini Man,” and even “Eternal Sunshine of the Spotless Mind”), “Swan Song” focuses more on the drama and cognitive concerns of cloning and brain-duplication (conscious and subconscious mirroring) than action, adventure, and the out-of-this-world nature of the science-fiction components.
What Movies Will It Remind You Of?: Swan Song has the understated, contemplative sci-fi of stuff like Her , Ex Machina , Morgan and Eternal Sunshine of the Spotless Mind .
If Cleary’s prologue evokes memories of the meet-cute from “Eternal Sunshine of the Spotless Mind” in the process, that also proves to accurately foreshadow a movie that uses a fanciful procedure as scaffolding for a story about someone trying to pave over their deepest pain.
